    摘要： An inner wheel skirt panel centrally located under the body of a vehicle reduces overall vehicle drag by inhibiting air from otherwise being displaced laterally inward by the passing wheels of the moving vehicle. Maintaining air to remain generally static while passing under the vehicle through the central open-space between the wheels increases the effective air pressure developed immediately behind the vehicle to reduce overall drag developed between the front and rear of the vehicle.

    摘要： An aerodynamically optimized drag-reduction means and method for optimal minimization of the drag-induced resistive forces upon a terrestrial vehicle wheel, where the drag-induced resistive moments on wheel surfaces pivoting about the point of ground contact are reduced, and the vehicle propulsive forces needed to countervail the resistive forces on the wheel are reduced. The drag reduction means includes: a streamlined wheel cover positioned on a vehicle to shield the faster moving upper wheel surfaces from headwinds; a streamlined wind-deflecting fairing positioned on a vehicle to shield the faster moving upper wheel surfaces from headwinds; an engine exhaust pipe disposed on a vehicle whereby exhaust gases deflect headwinds to shield the faster moving upper wheel surfaces of an automotive wheel; an automotive spoked wheel having streamlined oval-shaped wheel spokes arranged in one or more rows for greater axial strength; a streamlined tailfin rotatably attached to a wheel spoke, which thereby may pivot about the spoke in response to varying crosswinds; and a tire having streamlined tread blocks arranged in an aerodynamic pattern.

    摘要： A hydraulic servovalve is controlled electrically through electromagnetic means. Electrical currents applied to force motors determine the relative position of a single, displaceable control assembly within the valve. Displacive movement of the control assembly changes, in reciprocal proportion, the inlet and outlet flow-metering clearances in each of the chambers of this open-passage type valve. The position of the control assembly determines the inlet and outlet flows within, and, therefore, the net flow through, each chamber. Moreover, since the chambers are each connected (either directly, or through a flow-impeding orifice) to one of the control ports, the position of the control assembly thereby determines the control flow delivered by the valve. Generally, both hydrostatic and hydrodynamic forces within the valve are balanced against corresponding forces, all acting upon the control assembly. However, any internal unbalanced hydrodynamic forces--which arise in proportion to control flow--are compensated by opposing hydrostatic forces, creating a naturally stable servovalve over a wide range of operating conditions.

    摘要翻译： 液压伺服阀通过电磁装置进行电气控制。 施加在电动机上的电流决定了单个位移控制组件在阀内的相对位置。 控制组件的移动运动以相互比例的方式改变该开放式阀的每个室中的入口和出口流量计量间隙。 控制组件的位置确定每个室内的入口和出口流量，以及因此净流量。 而且，由于这些室各自连接（直接地或通过阻流孔）到控制端口中的一个，所以控制组件的位置由此确定由阀传递的控制流。 通常，阀门内的静水力和流体动力都与作用在控制组件上的相应力平衡。 然而，与控制流量成比例地产生的任何内部不平衡流体动力 - 通过相对的静水力补偿，在宽范围的操作条件下产生自然稳定的伺服阀。

    摘要： Aerodynamic fairing devices divert rising headwinds lifted over the top of a truck more laterally outwards to reduce vehicle drag. Embodiments include a truck cab roof mounted fairing, a streamlined truck cab roof, a fairing visor disposed on either cab roof fairing or on a streamlined truck cab roof, and a forwardly open-box sidewall assembly disposed on an upper portion of the front wall of a cargo box of a truck or semitrailer.

    摘要： An inwardly disposed vehicle skirt panel assembly disposed laterally inset toward the longitudinal centerline of the vehicle. The vehicle skirt panel assembly is suspended underneath a rearward body component of a truck or semitrailer, extending forwards in front of a rearward wheel assembly. The vehicle skirt panel assembly stabilizes otherwise laterally displaced air passing under the central portion of the moving vehicle, further increasing the effective air pressure developed immediately behind the vehicle. Maintaining air generally static while passing under the vehicle increases the effective pressure developed immediately behind the vehicle to reduce drag thereon.

    摘要： A longitudinally tapered wheel spoke having a thin aerodynamic cross-sectional profile proximate to the wheel rim and tapering to a round profile toward the central hub, with the tapered section optimized to minimize drag against a combined headwind and crosswind impinging upon the primary vehicle-drag-inducing uppermost region of the wheel assembly.
